Palm oil is a vegetable oil, also known as palm oil, which is derived from the palm fruit (Elaeis Guineensis) of the oil palm tree.It is the second largest edible oil after soybean salad oil. In addition, brown oil is also used as biodiesel. Malaysia and Indonesia are the world's leading producers of brown oil. Palm oil is an important part of the world oil market. At present, it accounts for more than 30% of the world's total oil production. Oil palm is a kind of crop that blossoms and bears fruits all the year round and has harvested all the year round. Commercial production of oil palm can last for 25 years. Affected by the expansion of global palm planting area and the increase of mature palm oil area, global palm oil production continued to increase in 2013, or reached a record high.
Palm oil is extracted from the Elaeis Guineensis of oil palm trees. The oil extracted from the pulp is called palm oil, while the oil extracted from the kernels is called palm oil. The components of the two oils are quite different. Palm oil mainly contains palmitic acid and oleic acid,the two most common fatty acids. The saturation degree of palm oil is about 50%. Palm kernel oil mainly contains lauric acid,and the saturation degree is more than 80%. Traditionally, palm oil only refers to crude oil (crude Palm Oil, CPO) and refined oil (Refined Palm Oil, RPO) extracted from palm pulp, and does not contain palm kernel oil. It has been used as a natural food for more than five thousand years. Palm oil originated in West Africa. Palm oil was introduced into Malaysia in 1870.
Oil palm is a kind of crop that blossoms and bears fruits all the year round and has harvested all the year round. Commercial production of oil palm can last for 25 years.Oil palm is the most efficient oil-producing plant in the world. In Malaysia, oil palm can produce up to 5 tons of oil per hectare. Oil palm produces five times more oil per hectare than peanuts and nine times more oil than soybeans. The average annual output of the mature oil palm in Malaysia is 3.7 tons of crude palm oil per hectare.Palm oil is a kind of vegetable oil, which can partly replace other oils, such as soybean oil, peanut oil, sunflower oil, coconut oil, lard and butter. Because of the relationship between palm oil and various oils.
Palm oil, also known as palm oil and palm peel oil, is a non-drying oil extracted from the peel of oil palm fruit. Oil palm fruit originated from the west coast of Africa. In the 1970s, Southeast Asian countries began to cultivate a large number of oil palm fruits. By the 1980s, the area and output of oil palm in Southeast Asia had surpassed that in Africa. Among them, Malaysia's production accounted for more than 50% of the world's production, and Indonesia's production accounted for about 20%. Hainan Island was introduced from Malaysia in the 1920s. Later, it was planted in Taiwan, Yunnan, Guangxi, Fujian and Guangdong provinces and regions, but the yield was not high. Since the 1970s, palm oil production has been the fastest growing of all kinds of vegetable oils. It has become the main edible oil in the world and occupies an important position in the international vegetable oil market. Due to the limitation of climate and other natural conditions, China's production has developed slowly. In the late 1980s, China began to import a large amount of palm oil, accounting for more than 15% of the world's palm oil trade.
The crude palm oil (CPO) and palm meal (PE) can be obtained from palm pulp by boiling, crushing and extracting. Meanwhile, during the crushing process, the palm fruit (i.e. palm kernels) is separated, crushed and the shell is removed, and the remaining kernels are crushed to obtain the crude palm kernels oil (CPKO) and palm kernels meal (PKE). Oil palm fruit contains two different oils, palm oil from pulp and palm kernel oil from palm seeds (kernels), the former of which is more important. All of these products have been effectively applied in food, chemical industry, agriculture and other fields. It can be said that palm is a good economic plant. After extracting from the above primary stage, crude palm oil and crude palm kernels oil are sent to the refinery for refining. After removing free fatty acids, natural pigments and odors, they become salad-grade oils-refined palm oil and palm oil salad oil.The refined palm oil is nearly colorless and transparent in liquid and nearly white in solid. In addition, according to the needs of different users, palm oil can be further fractionated and treated to form palm oleic acid (PFAD), palm liquid oil (OLEAN) and palm stearin (STEARINE or ST). Oil palm fruit contains more lipase, so the harvested fruit must be processed or fermented in time. Palm crude oil is easy to hydrolyze and produce more free fatty acids. The acid value increases rapidly, so it should be refined or extracted in time.
